Recently, I organized some of the most widely recognized classic trading systems in the trading community and found that there are reasons these methodologies have persisted to this day. Many top traders worldwide still use these systems for their trading, so today I want to discuss the logic behind these eight major trading systems.
Let's start with the most classic one—the Turtle Trading System. In 1983, the famous financial speculator Richard Dennis conducted an interesting experiment—he wanted to prove whether great traders are born or made. He recruited 13 people and taught them basic tra

While recently reviewing the history of cryptocurrency development, I noticed a pretty interesting phenomenon. When it comes to mining and early Bitcoin promotion, many people can’t avoid mentioning Wu Jihan. His experience really is worth discussing.
In 2011, Wu Jihan was still just an investment banking analyst, and at age 25 he was doing a typical 9-to-5 job. But that year, when he came across Bitcoin, it directly changed the course of his life. Unlike most people who treat Bitcoin as a speculative asset, he saw the underlying logic— the possibility of a decentralized financial system. He w

Recently, many beginners have been confused by the English letter units when looking at exchange market data. Actually, the symbols K, M, E, B, T on exchanges are abbreviations for numerical units. Once you understand these, you won't be fooled by the data anymore.
Let's start with the basics. 1K represents 1k, which should be easy to understand. 1M is one million, or 6 zeros. Next is 1E, which stands for 100 million—this is a common unit, often used when looking at trading volume or market capitalization. 1B is 1 billion, which is one more zero than 1E. The largest is 1T, representing ten tri

Recently, someone asked me about the difference between MA and EMA on Binance candlestick charts. Let me clarify once and for all.
First, let's talk about MA, which stands for Moving Average. Simply put, it’s the average closing price over the past few days, representing the average cost basis of the market during that period. For example, a daily MA7 calculates the average of the closing prices over the past 7 days. This gives an approximate idea of the market’s average cost during those days.
EMA, on the other hand, is different. It adds the concept of Exponential weighting on top of the MA.

Recently, I've seen many people claiming that 10 out of 12 mnemonic phrases in Satoshi Nakamoto's wallet have been cracked, suggesting an imminent brute-force attack. Let me tell you directly, that's completely false.
First and foremost: Satoshi Nakamoto's wallet does not have a mnemonic phrase at all. Why? Because the timeline doesn't match. When Satoshi mined the genesis block in January 2009, the BIP39 standard didn't exist yet. This mnemonic phrase scheme was only proposed in 2013. Think about it—back then, Bitcoin was still in its very early days. Satoshi used the original Bitcoin Core cl

Last month, I almost got tricked out of a sum of money. When I look back on it now, I’m still breaking out in a cold sweat. I want to share this experience, hoping it can help everyone avoid falling into the same trap.
This is how it happened — I saw a USDT balance in my wallet. The amount looked pretty legitimate; it was my salary. I wanted to withdraw it, but the system popped up asking me to pay a 20% activation fee to unlock the funds. At the time, I felt something was off. Only after I contacted the wallet customer service did I understand what was going on: I had connected to a fake cust

Recently, I’ve noticed that many people look at charts blindly searching for indicators. In fact, it doesn’t have to be that complicated. Today, I want to talk to you about something most people overlook—the most basic and direct rhythm language in the market.
Do you know what HH, HL, LL, and LH are? I dare say 90% of people have heard of them but don’t truly understand. Actually, these structures can be seen with the naked eye. I often mark them on charts just to help everyone quickly see the true framework of the trend—no need for fancy indicators.
Let’s start with a bullish scenario. HH is

Recently, more and more people around me are talking about gold. Some are starting to actively allocate, while others are still watching and waiting. Watching the gold price climb steadily, many are asking the same question: Is gold a good hedge? Today, I want to share my thoughts on this matter.
Gold prices have recently hit new highs. Many see others buying and follow suit, even going all-in at once, which is actually quite risky. I've noticed that people's understanding of gold often contains some contradictions. On one hand, they think it preserves value; on the other hand, they feel it's

Recently, I've been pondering a question. Buffett's famous quote, "Be fearful when others are greedy, be greedy when others are fearful," sounds simple, but in practice, it's incredibly difficult to execute.
I've personally experienced this dilemma. Sometimes, after a trade makes a profit, I start to fear the profits will shrink, so I hurriedly take profits and lock in gains. But then the market turns around and surges again, and that feeling of missing out is really uncomfortable. On another occasion, I stubbornly held my position, hoping to let the profits run further, only to see the market

Recently, someone asked me about the difference between full margin and isolated margin, and this question is quite common. So I’ll give a straightforward explanation.
Let's start with the core difference. Full margin means that all available funds in your account can be used as collateral, essentially forming a large pool where all positions share this capital. The advantage of this approach is that it provides a bigger risk buffer; as long as you don’t use excessive leverage, it’s generally less likely to be forcibly liquidated. I’ve seen many institutional users engaged in hedging who parti

Recently, I discussed technical analysis with some friends and found that many people's understanding of candlestick patterns still stays at a superficial level. I thought about organizing some practical insights.
It's interesting to note that our country’s stock market has been using candlestick charts since 1990 when trading started. Back then, research on candlestick patterns was mainly based on Japanese methods, with scattered studies on the statistical regularities of single, double, and multiple candlestick formations, but no systematic framework was ever established. To this day, many p

Recently, I’ve been exploring some historical stories about the Japanese stock market and discovered two very interesting figures. One is BNF, known as the trading god, whose real name is Takashi Kotegawa, and the other is CIS, reputed as the strongest retail investor. These two are not just friends; their experiences are quite similar—they both started trading in college and gradually grew their capital from small amounts to billions of yen.
What left the deepest impression is that they both rose to fame during the famous J-COM order mistake incident. That day, CIS made 600 million yen, but T

Recently, someone asked me about this again, so I might as well share my understanding today.
To be honest, many people confuse cross margin and isolated margin. The core difference lies in the risk diversification logic. In cross margin mode, all available funds in your account can be used as collateral, which greatly reduces the risk of liquidation. It's especially suitable for hedging or arbitrage strategies. As long as the leverage isn't too extreme, the likelihood of forced liquidation is generally low.
On the other hand, isolated margin works differently. In this mode, the margin for eac

Recently, I came across an interesting piece of American political gossip. Within Trump's team, there is a Chinese-American spokesperson named Steven Cheung. This guy is considered a prominent figure in the White House circle, but it seems the tide has turned recently.
Let's talk about this person. Steven Cheung is a Chinese-American who grew up in California. His parents are from Hong Kong and Mainland China, respectively, and he was born in the United States. In Trump's camp, he is among the most loyal members and also one of the highest-profile Chinese-American officials. This guy is known

I just saw a security breach on the ARB network, and it’s pretty alarming. According to Cyvers’s data, the attacker exploited a vulnerability in the proxy contract to steal $1.5 million in a single attack, involving the USDGambit and TLP projects.
The attack method was essentially targeting the ProxyAdmin permissions. The attacker deployed their own contract, updated the admin rights, and directly bypassed the original permission restrictions. The $1.5 million USDT on the victim’s address was transferred directly to the attacker’s wallet. I checked the transaction records, and the flow of fund

Recently, I've been analyzing Ethereum's price movement and have noticed some interesting patterns. Over the past few months, the price has been oscillating below $2000, being hammered down along with Bitcoin, and investors seem eager to sell.
I've observed a clear technical pattern: the price has been stuck around $1977 for a long time, with noticeably weak upward momentum. The current trend looks like it's forming a symmetrical triangle, with the price being squeezed between two trendlines. This kind of triangle usually indicates that the market is brewing for a big move, but the direction h

I just recently realized something: many people, including myself, have been neglecting roof maintenance. It wasn't until I saw dark streaks and moss start to appear on my own roof that I truly understood what "small problems become big troubles" means.
Roof cleaning is definitely not just for appearance. I found that algae and moss trap moisture on the tiles, and over time, the entire structure can be damaged. Asphalt shingles can lose their protective layer, wooden shingles may start to rot, and even metal roofs can rust. The most frightening part is if the gutters are clogged with leaves, w

Recently, I came across a quite interesting market trend. An asset management firm submitted an application to the U.S. Securities and Exchange Commission to launch a series of ETF products tracking U.S. election results, called PredictionShares, planning to list on NYSE Arca.
The design logic behind this is actually quite unique. They break down each political election into separate fund products—two funds corresponding to the 2028 presidential election, each based on whether the Democratic or Republican candidate wins; similarly, for the 2026 Senate control and House of Representatives elect

I just noticed that Qualcomm's latest earnings report is quite interesting. Quarterly revenue hit a record high of $12.3 billion, with automotive chips surpassing $1 billion for two consecutive quarters—looking very impressive. But then Wall Street slapped it back, and the stock price plummeted 9% after hours. The only reason? Memory shortages.
Qualcomm CEO Cristiano Amon was very straightforward: "I'm very satisfied with the business; I just wish there was more memory." The second-quarter guidance was cut from $11.12 billion to a range of $10.2 billion to $11 billion, and earnings per share a

I just recently discovered that IG accounts can actually be switched between professional and personal accounts at any time. I wanted to share this little tip.
Previously, I changed my account to a creator account to use data analysis tools and advertising features, but after a while, I realized I didn't really need those functions. I just wanted to share my life simply. Later, I found out that switching back to a personal account on IG is super easy: open the app, go to your profile, tap the three-line menu in the top right corner, find "Creator Tools and Controls" (or Business Tools, dependi
